BaseAudioContext 接口在 Web 音频 API acts as a base definition for online and offline audio-processing graphs, as represented by AudioContext and OfflineAudioContext 分别。 You wouldn't use BaseAudioContext directly — you'd use its features via one of these two inheriting interfaces.

A BaseAudioContext can be a target of events, therefore it implements the EventTarget 接口。

  <div id="interfaceDiagram" style="display: inline-block; position: relative; width: 100%; padding-bottom: 11.666666666666666%; vertical-align: middle; overflow: hidden;"><svg style="display: inline-block; position: absolute; top: 0; left: 0;" viewbox="-50 0 600 70" preserveAspectRatio="xMinYMin meet"><a xlink:href="../API/EventTarget.html" target="_top"><rect x="1" y="1" width="110" height="50" fill="#fff" stroke="#D4DDE4" stroke-width="2px" /><text  x="56" y="30" font-size="12px" font-family="Consolas,Monaco,Andale Mono,monospace" fill="#4D4E53" text-anchor="middle" alignment-baseline="middle">EventTarget</text></a><polyline points="111,25  121,20  121,30  111,25" stroke="#D4DDE4" fill="none"/><line x1="121" y1="25" x2="151" y2="25" stroke="#D4DDE4"/><a xlink:href="../API/BaseAudioContext" target="_top"><rect x="151" y="1" width="160" height="50" fill="#F4F7F8" stroke="#D4DDE4" stroke-width="2px" /><text  x="231" y="30" font-size="12px" font-family="Consolas,Monaco,Andale Mono,monospace" fill="#4D4E53" text-anchor="middle" alignment-baseline="middle">BaseAudioContext</text></a></svg></div>

特性

BaseAudioContext.audioWorklet 只读 安全上下文

返回 AudioWorklet object, which can be used to create and manage AudioNode s in which JavaScript code implementing the AudioWorkletProcessor interface are run in the background to process audio data.

BaseAudioContext.currentTime 只读

Returns a double representing an ever-increasing hardware time in seconds used for scheduling. It starts at 0 .

BaseAudioContext.destination 只读

返回 AudioDestinationNode representing the final destination of all audio in the context. It can be thought of as the audio-rendering device.

BaseAudioContext.listener 只读

返回 AudioListener object, used for 3D spatialization.

BaseAudioContext.sampleRate 只读

Returns a float representing the sample rate (in samples per second) used by all nodes in this context. The sample-rate of an AudioContext cannot be changed.

BaseAudioContext.state 只读

Returns the current state of the AudioContext .

事件处理程序

BaseAudioContext.onstatechange

An event handler that runs when an event of type statechange has fired. This occurs when the AudioContext 's state changes, due to the calling of one of the state change methods ( AudioContext.suspend , AudioContext.resume ，或 AudioContext.close ).

方法

Also implements methods from the interface EventTarget .

BaseAudioContext.createAnalyser()

创建 AnalyserNode , which can be used to expose audio time and frequency data and for example to create data visualisations.

BaseAudioContext.createBiquadFilter()

创建 BiquadFilterNode , which represents a second order filter configurable as several different common filter types: high-pass, low-pass, band-pass, etc

BaseAudioContext.createBuffer()

Creates a new, empty AudioBuffer object, which can then be populated by data and played via an AudioBufferSourceNode .

BaseAudioContext.createBufferSource()

创建 AudioBufferSourceNode , which can be used to play and manipulate audio data contained within an AudioBuffer 对象。 AudioBuffer s are created using AudioContext.createBuffer or returned by AudioContext.decodeAudioData when it successfully decodes an audio track.

BaseAudioContext.createConstantSource()

创建 ConstantSourceNode object, which is an audio source that continuously outputs a monaural (one-channel) sound signal whose samples all have the same value.

BaseAudioContext.createChannelMerger()

创建 ChannelMergerNode , which is used to combine channels from multiple audio streams into a single audio stream.

BaseAudioContext.createChannelSplitter()

创建 ChannelSplitterNode , which is used to access the individual channels of an audio stream and process them separately.

BaseAudioContext.createConvolver()

创建 ConvolverNode , which can be used to apply convolution effects to your audio graph, for example a reverberation effect.

BaseAudioContext.createDelay()

创建 DelayNode , which is used to delay the incoming audio signal by a certain amount. This node is also useful to create feedback loops in a Web Audio API graph.

BaseAudioContext.createDynamicsCompressor()

创建 DynamicsCompressorNode , which can be used to apply acoustic compression to an audio signal.

BaseAudioContext.createGain()

创建 GainNode , which can be used to control the overall volume of the audio graph.

BaseAudioContext.createIIRFilter()

创建 IIRFilterNode , which represents a second order filter configurable as several different common filter types.

BaseAudioContext.createOscillator()

创建 OscillatorNode , a source representing a periodic waveform. It basically generates a tone.

BaseAudioContext.createPanner()

创建 PannerNode , which is used to spatialise an incoming audio stream in 3D space.

BaseAudioContext.createPeriodicWave()

创建 PeriodicWave , used to define a periodic waveform that can be used to determine the output of an OscillatorNode .

BaseAudioContext.createScriptProcessor()

创建 ScriptProcessorNode , which can be used for direct audio processing via JavaScript.

BaseAudioContext.createStereoPanner()

创建 StereoPannerNode , which can be used to apply stereo panning to an audio source.

BaseAudioContext.createWaveShaper()

创建 WaveShaperNode , which is used to implement non-linear distortion effects.

BaseAudioContext.decodeAudioData()

Asynchronously decodes audio file data contained in an ArrayBuffer . In this case, the ArrayBuffer is usually loaded from an XMLHttpRequest 's response attribute after setting the responseType to arraybuffer . This method only works on complete files, not fragments of audio files.

范例

Basic audio context declaration:

const audioContext = new AudioContext();
						

Cross browser variant:

const AudioContext = window.AudioContext || window.webkitAudioContext;
const audioContext = new AudioContext();
const oscillatorNode = audioContext.createOscillator();
const gainNode = audioContext.createGain();
const finish = audioContext.destination;
